There are as many methods for making sourdough starter as there are bakers. Classicists say flour and water is enough to begin fermentation. Others—like Peter Reinhart of The Bread Baker's Apprentice, who inspired this recipe—suggest adding fruit juice to kick-start things. Mostly, it's the environment that matters: Measure liquids to solids carefully, use filtered water, and use room-temperature ingredients to help bacteria and yeast flourish and multiply.
